That doesn't explain why you can't get into the
bootloader via RS232- 
the state of the bootloader pin is checked before any
user code is executed.


Yes I know. I couldn't fathom it out either...BUT I
got the same result on three boards. It was
conclusive. After swapping a CPU for a new one and
implementing the  fix in the errata sheet, everything
was OK. I have asked Philips (via a distributor) to
try the code out for themselveves.
